LOOK FOR FIREARlVIS.

Application filed January 15, 1908.

To all whom it may concem:

Be it known that I, THOMAS Kornnn, a subject of the Emperor of Austria-Hungary, residing at Ober-Ferlach, in Carinthia, Austria-Hungary, have invented certain new and useful Improvements in Looks for Firearms, of which the following is a specification.

This invention relates to an improved construction in hammer-looks of fire arms which enables the operator to release the hammer from its cocked position into a safety notch or the like without actuating the trigger. For this purpose the construction is such that a small lever is articulated to the tumbler or in those cases when the hammer disk itself takes the place of the tumbler, as is the case for instance in revolvers or like arms, to the hammer-disk. WVhen the hammer is overcooked beyond the full-cock notch the said small lever turns the beak of the sear out of the path of the tumbler or of the hammer-disk, respectively, so that the hammer can be released into the uncooked position without the beak of the sear catching in the cooking notch.

The accompanying drawing shows by way of examples of execution two hammer-locks provided with the said improved means or devices.

Figures 1 to 4: relate to a hammer-lock with a tumbler, the said lock being shown in Fig. 1 in its uncooked position, in Fig. 2 in the cocked position and in Fig. 3 in its overcooked position, while Fig. 4 represents the said small lever on a large scale. Figs. 5 to 7 represent a hammer-lock in which the sear catches direct in the notches of the hammer-disk, the look being represented in Fig. 5 in the uncooked position, in Fig. 6 in the cooked position and in Fig. 7 in the overcooked position.

In a recess 0 of the tumbler d or as the case may be of the ha1nmerdisk (Z is arranged a small lever Z) provided with a pivot pin a. When the look is in its uncooked position, see Figs. 1 and 5, the said lever is inactive and comes to lie close to the lateral wall a of the said recess 0.

When the lock is being cocked, see Figs. 2 and 6, the tumbler or the hammer-disk is turned with the effect that the second lateral wall a of the recess 0 comes into contact with the small lever b and carries it along Specification of Letters Patent.

during the last part of its turning motion. During this motion the extremity of the small lever Z) that projects somewhat outside of the tumbler or of the hammer-disk engages in a recess f provided in the sear-beak 6 without however preventing the same from catching in the cocking-notch g.

If now the lock being in its cocked position, the tumbler (Z or the hammer-disk (Z will be overcooked beyond the cooking notch g by means of the hammer, see Figs. 3 and 7, the small lever Z) that bears against 'the lateral wall 0 of the recess 0 and therefore being obliged to follow the movement of the tumbler or of the hammer-disk respectively, movesthe beak e of the sear downward, so that now the hammer can be released and therefore the tumbler or the hammer-disk respectively brought back into their uncooked position, without the beak of the sear being caught in the cocking-notch, because the small lever b will release the beak of the sear only after the lateral wall 0 of the recess 0 has come in contact with the same lever Z) and carries it along with the same and this operation takes place only after the cooking notch has already passed the beak e of the sear.

Claims:

1. In hammer locks for fire arms, in combination, a pivoted hammer having half and full-cook notches in its edge, a movable spring-pressed sear having a beak to engage in said notches during the movement of said hammer and means carried by said hammer to disengage said sear from the full-cook notch when the said hammer is moved to overoocked position, said means having operation to hold said sear away from the full-cock notch during the movement of the latter past the sear upon the restoration of the hammer to inactive position.

2. In hammer locks for fire arms, in combination, a pivoted hammer having half and full-cook notches in its edge, a movable spring-pressed sear having a beak to engage in said notches during the movement of said hammer, said sear having a recess in its edge terminating near the beak, a lever pivoted upon said hammer and having a projecting end portion movable in the recess and formed to engage the beak and to move the same away from the full-cock notch when the hammer is moved to overcocked position and means for restricting the pivotal play of the lever in either direction.

3. In hammer locks for fire arms, in combination, a pivotal hammer having a recess in one side thereof and having half and full cock notches in its edge, a movable springpressed sear having a beak to engage in said notches during the movement of said hammer, said sear having a recess in its edge terminating near the beak and a lever pivoted in the recess of the hammer and having its pivotal movement limited by the side walls of the recess in said hammer, said lever having a projecting end portion movable in the recess in the scar and which engages the beak to move the same away from the full-cock notch when the hammer is moved to overcooked position and which maintains said beak in such relation during the passage of the full-cock notch thereby when the said hammer is being restored to normal inactive position.

4. In hammer locks for firearms, a movably mounted hammer having means for effecting a half and full cock operation, a spring-actuated sear having a portion to engage said means during movement of the hammer, and means carried by the hammer to disengage the sear from a full cock position when the said hammer is moved to over-cocked position and also operating to hold said sear away from the full-cock effecting means when the hammer is restored to inactive position.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

THOMAS KoFLER.
